CUSHION-HEEL.

Application led January 19, 1920.

To @ZZ whom it may concern.'

Be it known that I, Louis STEIN, a citizen of the United States, residing at Vashington, in the District of Columbia, have invented new and useful Improvements in Cushion-Heels, of which the following is a specii'ication.

The object of my present invention is the provision of a cushion heel, formed of rubber or equivalent material, andV embodying such a construction that it is possessed of good wearing quality, and is efficient in its cushioning action, and is adapted, by virtue ofits calhs and its `suction provision, to take secure hold of the ground when it is neiv,

- and also after it has been Worn to a considerable extent. Y

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described, and definitely claimed.

corresponding In the accompanying drawings, hereby made a part hereof:

Figure l is an inverted plan of my novel rubber heel. Y

Fig. 2 is an elevation of one side of the same.-

Fig'. 3 is an elevation of theopposite side ofthe heel.

Fig. 4 is a detail section taken in the plane indicated by the line 4-4 of Fig'. l.

Figi'. 5 is a detail section taken in the plane indicated by the line 5-5 of Fig. l.

Fig. G is a plan of the heel.

Fig. 7 is a transverse central section of the same.

`Similar numerals of reference designate parts in all of the views of the drawings.

My novel heel is formed of one piece of rubber, and is slightly concave at its upper side, the central portion of which is flat, so that when applied the top edges of the heel Will bear solidly against the under side' of av leather heel lift, as Willalso the central portion of the upper side. At the under side of its' forward portion and at opposite sides of its longitudinal center, the heel is provided ivith two annular projections l, the opening 2 in which is extended Vup into the body of the heel, so as to'contribute to Specification of Letters Patent.

the suction capacity of the projections l, and at the same time admit of the heel being readily nailed to a shoe.

Disposed diagonally in the rear portion of the underside of the heel, and adjacent to one of the rear corners thereof, is an elongated suction chamber 3, and in rear of said chamber is a. diagonal calk 4. In front of the chamber 3 is a comparatively long' diagonal calk 5, which latter is recessed at 6 to facilitate the driving' of nails through the apertures T in the recesses 6. The calk 5 is of a less depth than the calk4, and it will be noticed in this connection that the projections l are preferably of a less depth than the calk 4.

The heel, characterized as stated, is molded or otherwise formed iii one piece, of rubber or other equivalent material, and in use is opposed and nailed to a heel lift in the ordinary Well known manner, and With quite ras much facility as an ordinary rub# ber heel. In the practical use of the heel, it will be apparent that theprojections 1,*by the suction they afford, will take secure hold of a pavement and prevent slipping. In this thel projections 1 Will be assisted bythe rear calli 4, and the said projections 1 and the calk 4, Will afford adequate cushioning` means. In its gripping` and cushioning ac- Will be materially assisted by the adjacent chamber 3, and after the call( 4 has become Worn, it will be assisted in its gripping action and also in its cushioning action, by the-calk When the calks 4 and 5 as Well as the projections 1 are worn to the body of the heel, it will be apparent that the heel Will still be possessed of suction capacity by reason of the openings 2 extending up into the body of the heel andthe chamber 3 vthat is originally formed in said.

under side. It will further be apparent.

forth, the heel is susceptible of being produced quite as cheaply as an ordinary rubber heel.

Havingl described my invention, what I claim and desire to secure by Letters-Patent, is: Y

A cushion heel concave and having a flat central portion at its upper side and also having at its undersidea diagonali elongated l0 recess adjacent to and spaced from one rear corner of the heel, a diagonalcalk disposed in rear of said recess, and a diagonal call; disposed in front of the recess and having recesses and nail holes in communication therewith, theI second-named diagonal calk 1 being of a less depth. 4than the first-named diagonal calk.

In testimony whereof I aliix my signature.

LOUIS STEIN.
